Contraction driven cell crawling

The two main active processes allowing cells to crawl are myosin contraction and actin polymerization. We first show that these two mechanisms are complimentary allowing cells to handle such fundamentally different tasks as pushing and pulling. Then we focus on contraction dominated crawling involved, for instance, in motility initiation, and show that this mechanism ensures an almost optimal trade off between efficiency and cost.
